Red Island Volcano
Red Island (or Red Hill) is a lava dome volcano in the Salton Trough, and part of the Salton Buttes, the only active volcanoes in Southern California. It is located in Imperial County, California. It contains two lava domes, Prospect Dome and Alamo Dome.[1] The domes have been dormant for 2,000 to 8,000 years. The saddle between the domes, about 50 feet (15 m) below the summit of each dome, is a parking lot for county park visitors.
